Consecutive treatment of methyl-substituted quinolinium and 2,6-diarylpyrilium perchlorates with sodium ethylate and equimolar amount of anhydrous cadmium(II) trifluoroacetate gives 2- and 4-methylenecadmium-containing salts of the above heterocyclic cations in 80-97% yields. The reactions of the cadmium-containing quinolinium and pyrilium salts with hydrochloric acid, acetic anhydride, mercuric trifluoroacetate, SnCl2, and nickel(II) trifluoroacetate, resulting in substitution of the CdOCOCF3 group by hydrogen, Ac, HgOCOCF3, SnCl, and NiOCOCF3, respectively, were studied.

Kinetics of the monomercuration by the active methyl groups of 2- and 4-methyl-containing salts of quinolinium, pyridinium, benzothiazolium, and pyrrilium with mercury(II) acetate and trifluoroacetate in a mixture of anhydrous ethanol and acetonitrile (3:1) at 50-70degreesC were studied by means of acid-base potentiometric titration. The apparent second-order rate constants of these reactions were estimated, and factors affecting their rate were considered. A mechanism of the reactions was offered.
